摘　　要：通过塑性混凝土抗压、劈拉和抗折试验,在掺加粘土和膨润土的情况下,重点研究了水泥用量对塑性混凝土抗压强度、劈拉强度和抗折强度的影响。试验结果表明,在一定范围内增加水泥用量可以提高塑性混凝土的强度,降低塑性混凝土的脆性,合适的水泥用量在120 kg/m3左右。另外,尺寸效应对塑性混凝土抗压强度和劈裂抗拉强度的影响不明显。Based on compression, splitting and bending tests on plastic concrete, the effect of cement content on the compressive, splitting and bending strengths of the concrete is studied herein for the plastic concrete mixed with clay and bentonite. The test result shows that increasing the cement content in a certain range can enhance the strength of the concrete and decrease its brittleness. The appropriate cement content is about 120 kg/m3. Furthermore, the size effect has only less effect on the compressive, splitting and tensile strengths of the plastic concrete.
